Note that a *tree column* renderer yields * the *text* of the node. The lines and icons are produced by configurations. See * below for more information. * * **NOTE:** In previous releases, a string was treated as a method on * `Ext.util.Format` but that is now handled by the {@link #formatter} config. * * @param {Object} value The data value for the current cell * * renderer: function(value){ * // evaluates `value` to append either `person' or `people` * return Ext.util.Format.plural(value, 'person', 'people'); * } * * @param {Object} metaData A collection of metadata about the current cell; can be * used or modified by the renderer. Recognized properties are: `tdCls`, `tdAttr`, * `tdStyle`, `icon`, `iconCls` and `glyph`. * * For the standard grid column metaData propertyes see {@link Ext.grid.column.Column#cfg-renderer column renderer} * * To change the icon used in the node, you can use the glyph metaData property as below. * * You can see an example of using the metaData parameter below. * * renderer: function(v, metaData, record) { * metaData.glyph = record.glyph; * return v; * } * * or * * renderer: function(v, metaData, record) { * metaData.icon = record.icon; * return v; * } * * @param {Ext.data.Model} record The record for the current row * * renderer: function (value, metaData, record) { * // evaluate the record's `updated` field and if truthy return the value * // from the `newVal` field, else return value * var updated = record.get('updated'); * return updated ? record.get('newVal') : value; * } * * @param {Number} rowIndex The index of the current row * * renderer: function (value, metaData, record, rowIndex) { * // style the cell differently for even / odd values * var odd = (rowIndex % 2 === 0); * metaData.tdStyle = 'color:' + (odd ?
